PROJECT ALERT NOTICE (IN) Flooding on the lower Wabash River

Date: Thu, 25 Apr 2013 08:36:46 EDT

Summary: Moderate to major flooding continues on the lower Wabash River.

Moderate to major flooding continues on the lower Wabash River with the crest close to Riverton, IN at this time. 1-2 inches of rain fell across central Indiana yesterday including the central Wabash basin contributing to already oversaturated conditions in that area. The crest at Riverton should come later this morning and is predicted to be the highest since 1943 according to the National Weather Service (NWS). Predictions downstream show a more moderate level at this time from Vincennes to New Harmony.

The USGS has 2 crews (4 people) out measuring flow at Vincennes and further downstream at Mt. Carmel, IL today. Officials in Vincennes are keeping a close eye on the Brevoort levee which protects the city from the floodwaters of the Wabash. They have described ongoing seepage of water through the levee and are quoted to have "major concerns" according to several news sources. The crest is expected around Saturday in this area.

All gages are working correctly at this time across the state and have accurately recorded all peaks. The Indiana office has made 24 special measurements of discharge during this event. The USGS will continue to interact with the NWS, U.S. Army Corps of Engineers, state, and local officials for the duration of flood conditions.
